Question

Arrange the following events of muscle contraction in the sequence :
(1) Generate an action potential in the sarcolemma
(1) Form a cross bridge
(*) Release a neurotransmitter (Acetylcholine)
(iv) Release of calcium ions in sarcoplasm
(v) Pulls the attached actin filaments towards the centre of "A" band
(vi) Remove the masking of active sites for myosin
The correct option is :-
Oi-i-ii-iv-» >vi
O iiiv>i-ii--vi—v
O i-i-v ii-> vi
Ouiii-iii-​

Answer 1

I will write  the whole sequence,

1.  Release a neurotransmitter.

2. Generate an action potential in the sarcolemma.

3. Release of calcium ions in the sarcoplasm.

4.  Remove the masking of active sites for myosin.

5. Form  a cross bridge.

6. Pulls  the attached actin filaments towards the centre of "A" band.
